Telescopic este wagon

Affiliated technical field

The utility model relates to a kind of telescopic este wagon of light and handy, convenient and suitable travelling.

Background technology

Along with people's living standard constantly improves; the reinforcement of the consciousness of global environment protection especially recently; increasing people are considering that the automobile that rolls up brings problems such as people's city noise that trip easily and fast brings simultaneously, aerial contamination, traffic congestion and energy scarcity, the many folding bicycles that occur on the therefore recent home market.But present most of folding bicycle and to exist operation as CN2283606Y box-type folding portable bicycle, CN2283606Y Foldable minitype mini-motorcycle, the collapsible cart CN3385017 of CN1403336A folded bicycle complicated, carry factors such as inconvenience, therefore in the box-type tricycle (patent No.: ZL98248138.1) and box-type folding car (number of patent application: 2006201753911) generation the utility model on the basis, a kind of easy and simple to handle, telescopic este wagon of being fit to carry.

This utility model purpose is to provide a kind of telescopic este wagon of light and handy, convenient and suitable travelling, it not only has the same fast speed characteristics of automobile, there is contraction to close again and becomes boxed-section shape, the advantage that is easy to carry about with one, carries and pile up, and it is rational in infrastructure, operate more conveniently, and can realize according to the corresponding annex of the different increase in demand of people.

Summary of the invention

For achieving the above object, telescopic este wagon of the present utility model, mainly form by major parts such as back board, the seat grillage that has slide-and-guide groove (bar), wheel-mounted forward and backward wheel carrier, Power Component, assembly pulley and annex, and it is hinged between back board, seat grillage with axle, forward and backward wheel carrier front end is provided with slide block, and the guide groove (bar) that is contained in the oblique forward and backward under the seat plate respectively upward links together them.Available cable wire couples together slide block through pulley, the hinge wheel that in the middle of the seat grillage and two ends are provided with on the axle.

Principle of work, being angle between upset back board and seat plate is the seat shape, and the forward and backward wheel carrier slide block that slides makes front and back wheel lay respectively at the front and back lower position of seat along the guide groove (bar) of the oblique forward and backward under the seat plate is mobile respectively, fix with backing pin, insert handlebar, connect and take driving for the occupant after brake (can adopt the line brake) forms car; Take off backing pin and shrink and to be buckled into boxed-section shape and can to carry, also can utilize the wheel that exposes casing to push away, draw walking.And can by cable wire make back board rotate and the contraction of wheel synchronously.

Description of drawings

Accompanying drawing 1,2 is the example of this utility model.

Accompanying drawing 1 is the front view of telescopic este wagon.

Accompanying drawing 2 is the upward view of telescopic este wagon.

Below in conjunction with accompanying drawing and example the utility model is further specified.

1. front wheel carriers among the figure, 2. back board 3. can be rolled over handrail, 4. seat grillage, 5. handlebar, 6. rear wheel frame, 7. pedal frame waits annex to form.

The specific embodiment

In Fig. 1, its construction features mainly are by back board 2, the seat grillage 4 that has slide-and-guide groove (bar), front wheel carrier 6, rear wheel frame 1, Power Component, parts and annex compositions such as assembly pulley, and back board (2), have between the seat grillage (4) of slide-and-guide groove (bar) hinged with axle, front wheel carrier (6), rear wheel frame (1) front end is provided with slide block, the oblique sagittal guide groove (bar) that is contained in respectively under seat grillage (4) plate upward links together them, be the seat shape by being angle between the seat plate that rotates back board (2) and seat grillage (4) when using, and the front wheel carrier (6) that slides respectively, the slide block of rear wheel frame (1) front end respectively along under the seat plate tiltedly before, the back to guide groove (bar) move make front and back wheel lay respectively at the front and back lower position of seat (also can be tiltedly afterwards to guide groove (bar) rear end outwards be offset, can enlarge rear track like this), fix with backing pin, insert handlebar (5), take driving for the occupant after connection brake (can adopt the line brake) forms car, the person of driving is seated on the chair and moves ahead by pedal frame (7) the front wheel driving car that scrunches the band chain wheel; Take off close back board (2) and the front wheel carrier that slides (6), front wheel carrier (1) of backing pin and shrink and be positioned at seat plate frame (4) and become boxed-section shape to carry, also can insert handlebar (5) wheel that utilization exposes casing of doing in the case to shake hands and push away, draw walking.

In the middle of can be under the utility model seat grillage (4) plate and two ends are provided with axle, pulley is housed above it, hinge wheel, with being connected in front wheel carrier (6) with cable wire one end respectively, on the slide block of front wheel carrier (1) front end, converge on the middle cooresponding hinge wheel by cooresponding pulley on the plate two end axles, in the middle of can rolling over handrail (3), be connected with cable wire one end, the other end is connected under chair grillage (4) plate on the cooresponding hinge wheel of tween drive shaft, (if employing manual mode when rotating tween drive shaft, can increase a crank rotates, if adopt electronic mode, the available motor drive) one group of hinge wheel on the scrolling tween drive shaft, cable wire on the hinge wheel is respectively by pulley pulling front wheel carrier (6), the oblique sagittal guide groove (bar) of the slide block of front wheel carrier (1) front end under seat grillage (4) plate go up to slide, and pulling simultaneously can be rolled over handrail (3) makes front wheel carrier (6), flexible and the back board (2) of front wheel carrier (1) closes or opens.By the radius of design calculation pulley, hinge wheel and the point of connection of cable wire, make and to stretch out simultaneously or shrink and put in place.Also can directly rotate the interlock of back board (2), achieve the above object by cable wire.Can when automobile-used, unclamp backing pin and open automatically at chute (post) extension spring, alleviate people's work.Can turning slot be set in detent ends, be easy to automatically lock slide block.
